APPARATUS Fon FORMING To all whom it may concern:

` Be 'it ,known that I, ALBERT A. PAULY, a citizen of theriite'dp'States of America, residing at Youngstown, in the county ofMahoning and State of Ohio,

`have invented certain new and useful Improvements .inApparatusLforForming Building-Blocks and Artiicial Stohe from Plastic Material, ofwhich the follows jing is a, specification, reference being had thereinto the" accompanying drawing;

This invention relates to improvements in apparatus for formingvbuilding blocks and artificial stone from plastic material, and the`invention has for its object to provide a novel `apparatus foreconomically and expeditiously producing seasoned blocks and stoneshavingi qualifications lconducive lto immediate use.-

My' invention yaims Yto v provide platforms and molds arranged wherebythe molds can be successively used and their contents subjected totheuaction of steam, to season or cure the Vcontents ofthe molds priorto removing the same.` I locate a stripping device contiguous to themolds for removing the contents with considerable rapidity, whereby thepartial sea ksoned blocks orstones can be immediately transferred to aseasoning car adapted to travel adjacent to the platform. The seasoningcar, `whichis commonly styled a wet stone car, forms the subject matterof a patent granted to me April 2, 1907, No.y 849,160,. the car beingfitted with s'teampipes for subjecting the contents of the car to the4action of wet steam fora short periodl of time, whereby the stones orblocks will be thoroughly harclenedseasoned and provided With sufiicientwater-proof qualificationst withstand the forces of nature to which theyare subjected.

My inventionlparticularlyrcsides in the'novel arrangement of. theplatforms,` molds and stripping devices, whereby the production; ofartificialstones or blocks can be quickly accomplished, thereby not.necessitating the period of timegcnerally consumed for.

producinglartificial biiilding `blocks and stones.

The invention will be hereinafter more fully de scribed in detail withreferenceto' the accompanying drawings, wherein,

is a plan of the same, -FigfB'is a cross sectional view of an apparatuswherein thoteamsupply line for the wet stone cars is dispensed with,Fig. 4 is a plan of the same, Fig. 5is a longitudinal sectional view ofa movi able mold and a mold stripping device', Fig. 6 is an elevationpartly in'section of :tp-movable mold, Fig. 7 is a cross sectionalvviewfof the same.

which pallets 3 vare movably supported, the molding 'BUILDING-BLOCKS ANDARTIFICIAL PLASTIC MATERIAL.

used for the production of artificial. blocks or stones.

In some instances, these frames cah be movably supported, as illustrated5 of the drawings, the lframe being carried by a 'truck 4". In eitherinstance I provide means for subjecting vthe `,contents of the;

molding fra1nes,to'the action of steam or some heating medium,:wherebywhiletheplastic material is settling in'the molding frames,jthematerialcan be partially seasoned and placed in condition for more. safehandling, at the same time maintaining thegma terial in a conditionsusceptible to seasoning or cur,- ing, as will be presently described,`The heating meanswhich I have illustrated consists of4 providing eachmolding frame with a` steam supply pipe con- 4trolled by a suitablevalve 6.M The steamusupply pipes of the molding frames connect with avmain steam. supply pipe 7, preferably located beneath theplatv form 0rsupport l of the Vmoldinguframes. The molding frames `are provided withmovable doors 8, that after-the plastic material has been placed in theframes, can be closed, the valve-6 opened, and the, contents of saidframes'allowed to season.

To strip the molds or eject the material therefrom after the plasticmaterial has settled, I'arrange stripping devices bene'ath the platformsor supports of the molding frames, these devicesin a Vlarge plant beingoperated by steam or air, preferably steam from the main supply pipe 7,while in a Vsmall plant the stripping devices can' be manuallyoperated.' The stripping devices illustrated comprise hydrauliccylinders 9 having heads l0 provided with plunger-s ll, the headsl0`being movedupwardly toperniit of the' plungers ll elevating thepallets 3`within the molding `frames 2, and placing the plastic materiala sufilcient- 'distance above the frames ywhereby it can easily be.removed therefrom. A conventional form of valve 12 is used in connectionwith each cylinder for controllingthe raising and lowering of theplungers ll, rods 12 being'connected to the stems of the val-ves l2 `andextended up through the platforms l.\ so that the` valves may be`controlledirom the platforms.

As numerous `molding frames are used lor producing artificial blocks orstones, of various sizes, configurations and constructions, it is`necessary that meansl be provided for rapidly removing the partiallyfinished product. Therefore,` I have arranged between lthe v platformsor supports 1 of thle mo'lding frames atrack I4, upon which seasoningcars l5 can be moved and' loaded, either from the frames-upon oneplatform or rro both: One oi the cars which I preferably use isdisclosed in 'ny Patent No. 849,160, wherein shelves are arranged uponwhich the plastic material, either with -or without the 'pallets isplaced. The cars are provided with doors 16 which are closed after thecars l1iavalieen 1'illed,'whereby thelcontents of the cars 'can besubjected to the action of steam, tor rendering the stones and blockswaterproof. I preferably provide the cars with depending sputs 17, whichare adapted toaline with nozzles 18', carried by a steam supply pipe 19located centrally oi thetraek 14. The additional steam supply pipe 19 isprovided so that a loaded Canwaiting to be moved can besupplied withsteam, thus furthering the completion ofthe..

of cars are being loaded, the nozzles can be lett open,A and as the carsare successively moved forward, the' nozzles will aline with the spouts17 and supply the cars with steam. This may be the continuous method oiproducing concrete blocks and stones when the molding'frames are'successively used, from one end of the platforms or supports l.to theother end.

In Figs. 3 and 4. of the drawings, I have dispensed ith the steam supplypipe 19 and use ordinary cars Vin which the partially finishedv blocksand stones can be placed, then alterwards subjected to the action ofsteam or a heating medium in a specially constructed' building or kiln.In one of the molding trames, l'have illustrated a block 2Q heiligformed havingbeveled edges, while in other molds I have illustratedhollow concrete blocks and slabs as being formed, therefore, I do notcare to confine myself to the configuration oi the block or stoneproduced.

In Figs. 6 and 7, I have illustrate'l a movable molding frame as havinga plurality of movable drawers 2l corresponding to pallets, thesedrawers being particularly designed for holding plastic material in theiorm of slabs or plates. The molding trame is also provided with meansfor subjecting the contents thereof to the action oi steam. frames I canallow the plastic material to remain until it has been thoroughlyseasoned, and then use a stripping device, as illustrated in Fig. 5 oithe drawings, for ejecting the molded material from the molding frames,the location of the stripping device with respect to the plates when themolding frame is filled being immaterial. A 1

Desderatum of apparatus oi this type is the produc- In the movablemolding` tion of concrete building blo :ks and stones with considerablerapidity, therelore I. use steam or a suitable 'heatingl medium tofacilitate the formation of blocks and stones. Otherwise, it requiresconsidera-ble time to produce a block or stone that meets therequirements loi building speciiications.
